Odd behaviour on GtkEntry

[Kevin Handy <kth srv net>]

I've noticed something odd with GtkEntry on an old NDS Xterminal. Black
& White
only X Terminal, with all the x processes running on a RedHat Linux 5.1
box,
with the GTK libraries updated to a fairly current version (1.2.6).

The cursor is displayed to the right of it's actual position by about an
inch.
It makes it somewhat hard to edit data on this terminal. The cursor does
flash in the correct position while entering data, but immediately moves
off to the right.

Motif (lesstif) entry fields work correctly.

Any ideas?
